[Asia Pump Network News] 2BV water ring vacuum pump for the overall structure - pump coaxial single-stage pump. Xiaobian now through graphic mode, to explain 2BV water ring vacuum pump working principle and scope of application. 2BV water ring vacuum pump 1, 2BV water ring vacuum pump working principle as shown in the impeller 3 is eccentrically installed within the pump body, starting to pump a certain height of water injection, so when the impeller 3 rotation, the water by the centrifugal force The inner wall of the lower part of the water ring is tangential to the hub and rotates in the direction of the arrow. During the first half of rotation, the inner surface of the water ring is gradually separated from the hub, and therefore, between the impeller blades and The water ring forms an enclosed space. As the impeller rotates, the space gradually expands, the pressure of the space gas decreases, and the gas is sucked in from the suction port of the circular disk. In the second half of rotation, the inner surface of the water ring gradually approaches the hub, Of the space is gradually reduced, space gas pressure rises above the exhaust port pressure, the gas between the leaves from the disc exhaust port is discharged. So every rotation of the impeller, the space between the leaves suction exhaust, many of the space kept working, the pump continuously pumping or pressure to send gas. Due to the heat generated during work, the working water ring will heat up and part of the water and gas are arranged in a row. Therefore, in the course of work, the pump must be continuously supplied with water to cool and replenish the water consumed in the pump , To meet the pump's job requirements. When the pump exhaust gas is no longer in use, connected to the pump exhaust port gas-water separator, the exhaust gas and the part of the water discharged into the gas-water separator, gas and water separation, the gas discharged through the exhaust pipe, leaving Of water through the return pipe to the pump to continue to use. With the extension of working hours, working water temperature will continue to rise, this time from the supply pipe to supply cold water to reduce the working water temperature to ensure that the pump can meet the required technical requirements and performance indicators. Second, 2BV water ring vacuum pump use 2BV water ring vacuum pump for the overall structure - pump coaxial single-stage pump. Seal with mechanical seal, with a simple structure, easy installation, no oil, safe and reliable. 2BV water ring vacuum pump for pumping gas and humid steam suction pressure up to 33mbar absolute pressure (97% vacuum), when the vacuum pump in the suction pressure below 80mbar long-term work should be connected to cavitation protection tube To protect the pump, such as with the air Injector suction pressure up to 10mbar, the ejector can be installed directly on the vacuum pump suction port, as a compressor, the maximum pressure to 0.26MPa (absolute pressure). 2BV water ring vacuum pump is widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. As the process of gas compression is isothermal, it is not easy to explode when compressing and pumping flammable and explosive gas, so its application is more extensive.
